It should go like this:

(4z + 3) (3z - 4) / (3z - 4) (z + 2)

Then you just cancel out (3z -4) and (3z -4), and the final simplified form of this polynomial is:

(4z +3) / (z + 2)

Adam is building birdhouses that requires 1/2-ft-long boards. How many pieces that are exactly 1/2 ft long can be made from a bo

Julli [10]

Answer:

Step-by-step explanation:

Adam is building birdhouses that requires $\frac{1}{2}$ i.e 0.5 feet long boards.

Now, he has an $8\dfrac{1}{4}$ i.e. 8.25 feet longboard and wants to cut each 0.5 feet longboards.

We have to calculate the number of pieces of exactly 0.5 feet length that can be made from this 8.25 feet longboard.

Now, $\frac{8.25}{0.5}= 16.5$

So, there can be 16 whole board of exact length 0.5 feet. (Answer)

If kenny earns 142% of Benny's Salary, how mucho more does Kenny earn than Benny

Sergeeva-Olga [200]

Let Benny's salary = $ K

But kenny earns 142% of Benny's Salary

So, Kenny's salary = 142%of K

Kenny's salary =K $\times \frac{142}{100}$

Kenny's salary = 1.42K

Kenny's income exceeds Benny's by =1.42K - K =$0.42 K

% by which Kenny's salary exceeds by Benny's = $\frac{0.42 \text K}{\text K} \times 100$

% by which Kenny's salary exceeds by Benny's = 42%
